"il'rnrns IMPROVEMENT lN CORN-SHELLERS.

Specification forming part of Letters Patent No. 141,559, dated August 5, 1873; application filed March 18, 1873.

To all whom it may concern? Be it known that I, EDWIN L. HUTGHIN- SON, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Corn-Shellers; and I do hereby declare that the followin g is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings and to theletters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a machine for shelling corn, whereby the cornea-n be shelled from the cob by means of a single revolving sheller and the cobs delivered separately from the corn.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing in which Figure 1 is a side elevation of my machine with a part of the side removed. Fig. 3 is a transverse vertical section of the machine; and Figs. 2, 4, 5, and G are views of detached parts of the same.

Arepresents the outside frame or case which supports and incloses the working-parts. This frame is composed of two end standards with grooves, into which the ends of the sides fit, the frame being held together by bolts. B represents the sheller, which is made in the shape of the frustum of a cone. (3 is a guidebar, which is placed at an angle of about fortyfive degrees with the axis of the shelling-cone. E is an adjustable cap or plate, attached to the end of a spring, B, and is designed to hold the ear of corn down onto the cone while shelling. H is an opening in the frame at the lower end of the guide-bar (J, through which the cobs are discharged. 6 e represent wedgeshaped teeth on the shelling-cone B. The surface of this cone is made slightly concave, so as to bring the surface which is parallel to the guide-bar O in a straight line. The teeth 0 c are arranged so as to alternate in lines parallel to the bar 0. The g'uide-barC is so constructed that all points of its surface m which lie in right lines to the axis of the cone B will be in a plane which passes through or in front of that axis. The cap E is placedin such a position relative to the surface of the cone that its surface n will lie in or about a plane tangent to the surface of the cone; and

. the cap is also provided with one or more ribs,

0, 0n the under surface, which ribs stand at about right angles with the surface m of the guide-bar 0, and are designed to hold back and prevent the ear of corn from passing through until the corn is all off. The greater diameter of the cone B is provided with an enlarged rim, a, which acts as a fly-wheel. The journals 1; b of the cone are made tapering from the cone out, so that in manufacturing they may be cast in chills. The opening H is provided with two rubber or leather curtains, 70 k, which are cut so as to permit the cob to pass freely through them, and at the same time prevent the shelled corn from flying or following the cob through. The bearings to the cone B are provided with ribs 12 p, and an inside flange, r, which prevent them from getting out or turning around. The front journal b is carried out on a taper beyond the bearing for the purpose of fastening on a,pinion or crank. The spring It is secured and held in the desired position by pieces S and T. The piece S acts as a center around which the spring R springs, and from which, asfa center, it is caused to spring in the desired position. The piece T acts as a guide to the upper end of the spring, and also as a nut for a set-screw, 00, which gives the proper tension to the spring. The guide-bar O has a standard, 9, against which the spring R slides, and which acts as a guide for the spring. In the top or cover to the frameAis a suitable spout or hopper, D, to receive and guide the ears into the sheller, which hopper is inclined forward or toward the front journal to an angle of about -forty-five degrees. The internal gear N runs on a taper stud, f, and is arranged with a crank to be run by hand. The opening beneath the frame is fitted with inclined pieces, all but a small space for the corn to fall through.

The ears when fed into the hopper D fall down onto the teeth 6 e, which seize them and carry them against the guide-bar G, and pass them in an advancing and rotary motion through the machine, shelling the corn, and

Z L a discharging the cobs through the opening H, while the shelled corn falls down and passes out of the opening in the bottom.

The machine is arranged so as to run direct by removing the pinion and gear and applying a crank.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. The guide-bar 0 having the standard 9, for the purposes herein set forth.

2. The combination, with the spring R arranged to control the concave or plate E, of the central supporting-piece S, piece T, and adjusting-screw 00, substantially as set forth.

In testimony that 1 claim the foregoing as my own I affix my signature in presence of two Witnesses.

EDWIN L. HUTCHINSON.
